Paris was the main area of the first mass destruction caused by the Doomsday Group. The group made the destruction happen by gathering people for a rally above sewers filled with C-4 and gaz toxique (poisonous gas). When detonated, the C-4 caused catastrophic amounts of damage to the city and wounded countless people.

It was heavily implied that Paris had been hit by a nuclear bomb, like Hong Kong and Dar es Salaam, or possibly flooded like New York. A news site that the Flock visited showed the president of France giving a speech while wearing a hazmat suit.
